This inventionV relates toi means designed for test-ing the' tube of a locomotive superheater,l and comprehends a construction and arrangement of parts which permit the invention to be easily and quickly associated with or removed from the tube asthe occasi-onmay require, and accomplish the desired results inquick order.

The nature and advantages of the'inven- 1U tion will be better understood when the fol-` lowing detailed description is read in connection with the accompanying drawings,

' the invention residing in the construction, combination and arrangement of parts yas 151 claimed. 'V In; the drawings forming part of this vapplication, like numerals of reference indieA cate similar'partsfin the-several views, and*k Y j f v f accommodatea gasket VV24, so that when the wherein:

Figure 5 is an enlarged fragmentary view of the upper portion of the-device showing how the sliding head is mounted.

Figure .6 is a sectional view taken through Figure 5 and at a right angle thereto.

The device forming the subject matter of the present invention embodies a base plate or block which is provided with a slot or opening 11 to allow the same to be slipped over one of the tubes of the superheater to be tested. Supported by this basel or block 10 are spaced parallel standards or uprights 12, each formed with a fork-like extremity, with the branches 13 thereof passed through openings in the base 10 and secured thereto by nuts 14 threaded on said branches 'above yand below the base. The

the' ysubject matter upper end of each standard is slotted or cut l away as at 15 to slidably receive a bearing block 16, .the cut away portion 15 being closed by a transverse member or block 17 which is held in'position by means of suitable fastening elements 18. Thistransverse member 17 also supports an adjusting screw 19 which is utilized to adjust the bearing4 AS block 16 as the occasion may require. above stated, the base 10 is adapted to be slipped over one ofthe tubes of the super- Figure 1 is a view in elevation of one of heateiy the device including a slidable head 2O which cooperates with the base 10y for clamping the device in position for use. In other words,'the base platelO is adaptedto be slipped over the tube directly beneath the flange that is usually provided adjac-entthe upper end of the tube, and when the head 2O is moved into effective engagement with the upper endof the tube, the base plate 10 engagesA the flange abovey mentioned and therebyy holds the deviceA on lthe tube for use. The head 20 is adapt-ed to slide between the parallel uprights or standards 12 and is provided with a fluid passage or bore 21which confimunicatesrv witha port' 22l arranged at a `right angle to said passage, and which port accommodates a vfluid supply pipe 23. The underside 0f this head 2O is recessed to headl 2O is -moved downwardly to engage the adjacent end ofv the; tube with which the device is associated, a fluid-tight connection will be provided for' between the head and' tube, as will be readily understood. It might here be stated `that in testing the tubes of the super-heater, therey are two of such devices employed, which devices are associated with their respective tubes in a manner to allow the fluid from the pipe 23 to pass or circulate through the tubes and through said devices for-.the purpose intended.

While any suitable means may be ein-i ployed for controlling the movements of the head 20, I preferably make use of a U- shaped member 25, the parallel portions 0f which are indicated at 26 and arranged between the uprights or standards 12. The member is provided with spaced openings through which pass headed bolts 27, the openings therefor being` indicated at 28, and these bolts have their` lower extremities threaded into the head 20, as at 29. Now surrounding each bolt is a coiled spring 30 which provides a yieldable connection between the Ueshaped member 25 and the head 20., to hold this. head effectively seated Yagainst the particular tube with which it is used. For therpurpose of raising and low-v eringl the head I employ a lever 31 forked at Vone end., and the branches of this extremity are indicated at 32. Each branch is connected with the adjacent bearing block 16 above referred to by means of a bolt or the like indicated at 33, which bolt passes through the particular branch of the lever, a disk 34 carried by the U-shaped member 25 and the bearing block 16. This censtruetion and arrangement is clearly shown in Figure G. The level` pivots on these bolts 33, while the lever, or the b 'anches 32 thereof are riveted or otherwise suitably secured, as at 35, to the adjacent disks 2M. rlhere are two o these disks, one for each parallel portion 26 of the U-shaped menjiber, which porn tion provided with an opening to accommodate the disk, as shown in Figure (3. Coneminently, when the lever 31 is swung in one direction, the disks Bel are rotated to torce the U-shaped member dowiuvardly between the standards 153, thereby exerting a pressure upon the springs to move the head 2O into engagement with the adjacent tube and hold it so effectively associated therewith as to prevent. leakage ot fluid passing through the device.

1Vhile it is believed that from the foregoing` description the nature and advantages ol the invention will be readily apparent, I desire to have it understood that I do not limit myseli'l to what is herein shown and described, and that such changes may be resorted to when desired as fall within the scope ot' what is claimed.

Having thus described the inventioin what is claimed as new, is

1. A device ot the character described compi-isinel a base having a slot opening ae one side thereof, spaced standards rising from the base, a member supported by the standards for sliding' moven'ient therebetween, a head arranged between said standards and suspended from said member` a yieldable connection between the member and said head, a lever associated with said member for controlling` the movements et the latter between said standards, said head having a fluid passage arranged axially thereof7 and a tluid supply pipe connnuni.-

ating with said passage.

2. Means for testing` tubes of a superheater, comprising devices adapted Vto be supported on the tubes, each device includ ing a` base having,l a slot to receive one oil" said tubes, spaced uprights rising from the base, a substantially U-shaped member supported between the uprights for sliding movement, a head suspended from said U- shaped member for movement therewith and adapted to repose on the upper end of the adjacent tube, said head having` a fluid passage and a recess in the bottom ther-eet, a gasket embedded in the *alls of said recess to provide a Huid-tightconnection between the head and said tube, a fluid supply pipe communieatingI with said passage, a yield. able connection between the head and U- shaped member, and means for controlliup,- the movements of said member and holdingY the head elt'eet-ively seated against the tube.

In testimony whereof I atlix my signature.

JOHN K. HARTLINE.
